Just visited the TenRen in College Park and it's very nice. Unlike the TenRen in Rockville, this is a tea and light munchies cafe. If you're into bubble tea (YEAH!), there are many other flavors to try here.
We didn't get to try the food (has anyone eaten here yet?) but thought the cafe looked very nice, all except for the pop music playing which I'm sure was for the college kids but contradicts the feel of the cafe.
